How much time does it take for a circle to become round? None at all. It happened instantly.
More interesting question to me is why the hell some firmware boots take so long now. I know laptops from years ago much, much faster than what I have now, which is otherwise much faster than them. And the firmware initialization times for some servers I've seen seem completely obscene (on the order of minutes).
Windows is a bloated mess, so it's obvious there. As for anything POSIX, it's because UNIX is shitware; it took a long time to boot decades ago and it takes a long time to boot now, because more garbage has been piled on top. It's possible for a good operating system to boot in less than a second, however. People have simply been conditioned to accept this unacceptable state of affairs, no different than a TV that ta…

Probably because no one turns anything off anymore so the selection pressure is gone.
Has someone explored the area of writing software that spits out resume from disk images?
That exists for a long time now, but is technically not booting.
Because everything takes non zero time. If a state transition from turned off to booted takes no time then doesn't that mean there is no state transition at all? The only way for it to take zero time for a computer to boot is if it is already booted or there is no difference between an unbooted computer and a booted one.

Booting, as in detecting and initializing the hardware, including the RAM, should only be needed when hardware is changed, and even then it should be possible to cache the state of any unchanged parts.
